BACKGROUND OF THE INVENTION

The new invention pertains to baby swings, baby swing accessories and swing systems particularly related to; baby car seats, reels for adjusting swing height and simple swing hangers.

Babies especially enjoy the motion of a swing. Traditional Baby swings are well known commercially available products that are commonly offered in two main forms; 1) Baby swings for attachment to swing sets, and 2) Baby swings with their own support frame. In the current art, baby swings for attachment to swing sets have many of the same features as a traditional playground swing has, however the baby swing seating area is generally formed or structured to assist in supporting and preventing the baby from falling out of the seat. Some patents that teach the typical baby swing seating configurations are; U.S. Pat. No. 4,693,512 to Hobson, U.S. Pat. No. 5,334,099 to Marra et al., U.S. Pat. No. 5,533,934 to Miller and U.S. Pat. No. 6,474,736 to Brown. In these patents, their designated seat configuration is a requirement of the invention in order to establish the baby swing. Also in the current art, there are many popular baby swings having independent support frames with designated seating configurations. The swing is limited to a short height and a short swinging arc. Some patent examples of baby swings having their own support structures are; U.S. Pat. No. 6,343,994 to Clarke and U.S. Pat. No. 7,275,996 to Dillner et al. Although baby swings are known to be available in many shapes and forms, none of the previous mentioned patents teach the use of a baby car seat to establish the seating portion of the swing, each requires a custom seating portion.

Baby car seats are well known commercially available products used to safely position and support a baby in a vehicle during transportation. The car seat attaches to the vehicle's safety restraint system and it also has an independent harness restraint system for the baby. Baby car seats are made for two different age groups, infants and toddlers. Baby car seats made for infants under 12 months old are currently available in the market equipped with; a base portion that attaches to the vehicle's safety restraint system and a detachable car seat carrier portion. The detachable car seat carrier incorporates a pivotally adjustable handle that locks into positions to easily carry the car seat and baby. Baby car seats for toddlers are larger and formed to fit the vehicle seat, they are less portable and usually stay attached in the vehicle. Baby car seat dimensions and general geometry are essentially the same for the various model types currently available in the market. Many governments, including the United States, have mandatory laws requiring that all children must be seated in an appropriately rated car seat for transportation in an automobile. Laws also state that the owner cannot buy or sell a used car seat. During the growth of a child, the child's caregiver may own several different car seats having one primary functional use; most car seats are given away to family or friends or discarded.

There are known swing accessories that attach to a baby car seat. One swing product is currently offered under the trade name “SnugGlider” and consists of a small portable frame having a rigid mounting receptacle intended for use with only one particular car carrier model type. The rigid car carrier mounting receptacle pivots in the frame to create a short swing arc. There are also patents that describe the use of a car seat for a swing. U.S. Pat. No. 6,692,073 to Weathersby teaches an infant car seat carrier apparatus. The U.S. Pat. No. 6,692,073 patent teaches a base assembly much like the more traditional swings described above that requires their own support frame. The method of attachment of the car seat to the apparatus is by a rigid mount. The short swing arc center is positioned below the car seat, not from a point above the car seat, as is traditionally done. U.S. Pat. No. 7,037,205 to Bowman, describes an improved baby car carrier device having an integral swinging mechanism. U.S. Pat. No. 7,037,205 does not teach the use of existing car seats to create a swing, however it teaches a new type of car seat incorporating an integral swing mechanism that is stored in the handle portion. In all of the known existing swing accessories the car seat attaches to an integrated frame or base.

Slings are well known industrial products used for lifting or hanging heavy loads. Standard slings are available in different forms including a continuous closed loop. Standard sling materials include load rated woven strapping, chain, wire rope and ropes. Due to the closed loop geometry the sling can drape over an open object and the opposite end can thread through the draped loop end. When pulled tightly the sling rigidly secures itself to the bar with out the use of any hardware. The standard industrial sling is primarily used for supporting heavy loads and is not recognized for use with baby swings.

Many existing structures are suitable for supporting the weight of a baby swing. Some have open beams such as; a swing set crossbeam or a sturdy tree branch. Other existing structures that are suitable for supporting the weight of a baby swing have covered structural beams such as; structural features on buildings including, (floor joists covered by flooring, doorway headers covered by door casings, deck joists covered by decking, archways and ceilings covered by sheathing such as sheetrock as well as other structural support beams). The use of appropriate hardware is required to properly attach to the closed beam structures. Installation of common hardware normally requires appropriate tools such as wrenches or screw drivers.

BRIEF SUMMARY OF THE INVENTION

Therefore, it is an object of this invention to provide a new and novel swing accessory for use with existing baby car seats and existing overhead structures, establishing a new baby swing system. The baby swing system easily attaches to existing car seats and preferably infant baby car seat carriers where multiple methods of attachment can facilitate varying incline positions for the baby. The swing system safely and easily installs onto existing open overhead beam structures without the use of hardware, this is accomplished by knotting the sling's attachment end with a clove. Further, the new system exists in simple fixed length form and also a preferred variation having adjustable length to accommodate height variations of existing overhead beam structures and desired swing height. One or more reels are used to adjust the swing systems main cord length and therefore positional height of the swing from the ground. The reel also functions as a portable storage for the swing accessory cord length. A preferred reel has a locking retractable mechanism that is designed to support the swing loads, however, simple manual winding reels can also be used. Additional features to the accessory further include; optional hangers for installation into covered overhead support beams. A new and novel hanger design is easily installed by hand without the use of tools. Other features of the new baby swing system include ornamental attachments with optional recorded sounds having particular appeal to babies.

DETAILED DESCRIPTION OF THE DESIGN

The new baby swing system has numerous variations of embodiments, including combinations of; cord types, cord configurations, optional cord reels, practical attachment methods to the car seat carrier and configurations of fastening methods and hardware to overhead structures. The following detailed descriptions are intended to provide a general understanding of the main elements of the baby swing system as well as new or novel features of these elements as implemented in the preferred embodiments of the invention.

The cord assembly can exist in many material types rated for the swing system loading including; wire rope, nylon webbing, braided fabric rope, chain and variations thereof.

Cord assembly configurations consist of single or multiple main cord lengths that extend between the overhead support structure and the car seat carrier. Attachments to the car seat carrier may consist of the main cord and additional supporting cords or cinching straps that attach to the main cord. The additional cords and cinching straps secure to rigid portions of the car seat such as; the carrying arm, the pivot joint of the carrying arm and to the car seat carrier's base structures. The use of supporting cords and cinching straps will be further described below as they pertain to embodiments of the new invention.

Existing overhead structures are sturdy structures suitable to support the swing loading forces. Such overhead structures include; traditional swing set cross beams, sturdy horizontally growing natural tree branches and horizontal supporting beams installed in modern building construction such as, (floor joists, rafters, decks, interior door frame headers, and supported ceilings). Other custom made frame structures may also be suitable for supporting the new swing accessory. Fastening methods and hardware used for attachment of the swing system to these structures will be further described as they pertain to specific embodiments.

Simple embodiments of the invention are described in FIGS. 1, 1A and 1B. The swing system 1 is established by a cord assembly 2 that is secured to an overhead beam 3 and also secured to a baby car seat carrier 4. In these simple embodiments, the cord assembly 2 is a continuous loop where a first side of the loop 2 a is draped over the overhead beam 3 and the opposite end of the cord 2 b is threaded under the overhead beam and through the exposed opening of the first loop 2 a. The assembly is pulled tightly downward establishing a secured grip to the overhead beam 3. Now the second side of the looped cord assembly 2 b is capable of securing and attaching to the car seat carrier 4 in the following methods when the car seat carrier handle 4 a is in its upright locked position.

Referring to FIG. 1, the second side of the cord assembly 2 b passes under the front side of the car seat handle 4 a, and then loops around the backside of the carrier and further continues to wrap all the way around the front side of the carrier. The slack in the cord assembly is pulled upward toward the beam 3, resulting in the cord assembly 2 fully wrapping around the carrier handle, securing the cord to the handle, as shown.

The preferred installation of the cord assembly 2 to the car seat carrier 4 is depicted In FIGS. 1A front elevation view and 1B side elevation view. To install the cord in this method, the second side of the cord assembly 2 b passes under the front side of the car seat handle 4 a, and then loops around the backside of the carrier 4 c shown in FIG. 1B and further continues to wrap all the way around the front side of the carrier, then continuing back underneath the handle and finally wrapping around the backside of the carrier 4 c for a second time. Then the main cord assembly is tightly pulled upwards to remove the slack in the cord assembly resulting in the cord assembly 2 securely wrapping around the carrier handle while the second side of the cord assembly loop 2 b rests tight against the backside of the carrier base 4 c as shown in FIG. 1B, thus establishing a secure support and attachment of the cord assembly 2 to the car seat carrier 4.

An optional reel 5 is positioned along the main cord length. The optional reel 5 is for coiling the cord 2 for storage and for adjusting the cord length to establish desired height positions of the swing system 1. The optional reel 5 can be manual winding as described in the embodiment of FIG. 3, or the reel may have a spring loaded retractable mechanism as described in FIG. 4. The optional reel 5 can also have many configurations and positions along the cord assembly as will be further described as it applies to particular embodiments.

For added security, two cinching straps 6 are optional but will help to secure the main cord 2 to the car seat handle 4 a. Cinching strap 6 is made from nylon webbing having a grommet that the main cord 2 passes through to easily position the cinching strap 6 in a desired position along the cord length. One end of the cinching strap has a sewn in fitting. The other end of the cinching strap inserts through fitting and is pulled tightly around the handle 4 a. The cinching strap length contains opposing hook and loop grip for secure installation and removal of the cinching strap to the car seat handle 4 a.

The preferred material of the main cord assembly is ( 3/32-⅛ inch) plastic coated galvanized wire rope selected for its corrosion resistance, strength and small diameter. FIG. 2 describes the connection of two ends of a cord assembly 2 made from wire rope. Ends 2 c and 2 d of the wire rope have had the outer plastic coating removed. The wire rope ends 2 c and 2 d overlap each other by the length of the aluminum oval sleeves 7 used to connect the wire ends together. The ends of the wire install into the oval sleeves 7 as shown. The oval sleeves are secured by crimping with a special sleeve crimping tool. The secured joint is covered with a protective section of shrink tubing 8 to conceal the joint and to protect the user from sharp wire ends. Other means for connecting cord ends together that fall within the claims and true spirit of the invention are; linking rings, threaded fittings, hooks, latches etc.

FIG. 3 describes another embodiment of this invention that utilizes a manual winding reel assembly 10. A cord 11 has a continuous loop construction with two loop ends 12 and 13 that correspond to loop end 2 a and 2 b in FIGS. 1, 1A and 1B. The loop ends 12 and 13 install to the overhead beam and the car seat carrier in the same manner as the embodiments shown in FIGS. 1 and 1 a. The manual winding reel assembly 10 includes a reel 14 which is a single component, made up of a center diameter 15, two outer flanges 16 and two inner flanges 17. The cord 11 is installed through the central groove 18 and passed through the hole 20 on opposing sides, so that the cord 11 engages both outer grooves 19. The cord ends are joined together as shown in FIG. 2 to create the cord loop. The reel is positioned down the length of the cord as desired. To adjust overall cord length of the assembly 10 between loop ends 12 and 13; The cord length extending from the center diameter 15 of the reel to cord loop end 13 is wound around the reel 14 and captured in outside grooves 19. The cord length extending from the center diameter 15 and cord loop end 12 is wound around the reel 14 and captured within central groove 18. When the opposing load is applied to both loop ends of the cord, the reel supports the load due to the winding configuration of the cord around the reel. The reel 14 can contain the entire length of cord 11 when the reel 14 is centrally positioned on cord length. The preferred circumferential length of the cord in this embodiment is 20 feet.

A preferred configuration of the reel is one that has a locking, spring loaded retractable mechanism. FIG. 4 describes one embodiment of a single reel with locking retractable mechanism. The components of the reel consist of; An outer casing 30 providing structural rigidity, A flat wire constant force spring 31, An internal drum 32 supporting the cord 33, a compression spring 34 loading the locking button 35 against a cover 36 that threads into the outer casing 30 securing the assembly together. The flat wire constant force spring 31, would have an uncoiled length approximately the same length as the cord. The inside end of the flat wire constant force spring 31 would engage a slot positioned on the center of the outer casing 30 and the outside end of the flat wire constant force spring 31 would engage slots in the outside edge of the internal drum 32. The cord 33 is coiled around the internal drum 32. The internal drum has securing means to the inside end of the coiled cord. The locking mechanism incorporates the use of a compression spring 34, a hardened pin 35 having a spline 37, (or even a hexagon shape not shown). The spline 37 normally engages the female spline 41 in the outer body 30 and also engages a central hardened spline insert 38 positioned within the internal drum 32, the compression spring 34 loads the assembly thus locking the spline 37 to spline insert 38 to keep the desired cord 33 length in place. To release the lock, the side button 35 would be activated against compression spring 34 to temporarily disengage the spline 37 from the internal drum socket 38. The lock would re-engage when the side button 35 was released. When the lock is disengaged the extended portion of the cord 33 would naturally want to retract into the body 30 due to the spring load generated by the flat wire spring 31. Also, when the lock is disengaged the desired cord length can be extended.

For versatile attachment, the reel housing incorporates a mounting eye 40 and the cord 33 may be equipped with a safety latch hook 39 or vice versa for connection to the car seat carrier and overhead supports. The latch hook 39 can also connect to eye 40, creating an adjustable length continuous loop for connecting the swing assembly together as is described in the embodiments of FIGS. 1, 1A and 1B. The cord 33 can alternatively be fixed to the reel outer casing creating a permanent continuous cord loop as indicated in FIGS. 4A and 4B for double reel designs

A second opposing retractable cord reel mechanism can be incorporated making it a double reel. The double reel can be positioned side by side as shown in FIG. 4A, or in a stacked position as shown in FIGS. 4B and 4C, where both reels are encased inside a common housing. In these alternate reel embodiments, the cord 33 extends to connect to the second reel for use in both retractable assemblies, creating a functional loop for attachment to the car seat carrier as is described as item 2 a and 2 b in embodiments of FIGS. 1, 1A and 1B, and items 12 and 13 in FIG. 3. Alternatively, each reel can have its own cord for independent attachment to the car seat carrier or the over head hanger. For added appeal to babies, battery operated digital music devices and ornamental covers are installed onto the reel casings of embodiments in FIGS. 3, 4, 4A 4B and 4C (not shown).

The embodiments described so far have been shown to connect to open overhead beams. The new swing system includes hardware that connects to overhead structures such as floor joists, door frame headers decks and sheathed ceilings that do not have open top beam structures. Traditional hardware can be employed for hanging the swing system such as eye-bolts;, eye and hook shaped lag screws, bolted on brackets comprising connecting hooks or rings and other hardware typically used to hang swings including porch swings and hammocks.

One new preferred swing hanger design is described in FIG. 5. The novel feature of the hanger 50 is that it can be installed by hand without the use of other tools into a wooden structure 51 (shown in cross section, having a top sheathing cover 51 a). This particular hanger embodiment is capable of being installed on the side of the beam 52 or the bottom of the beam 53. The formed hanger geometry 55 provides a lever arm and comfortable hand grip to torque the screw portion 54 into the wooden structure 51 without the use of any other tools. Screw portion 54 is self tapping into the wooden structure, no drilled hole is required. When the hanger 50 is mounted to either the side of the beam 52 or the bottom of the beam 53 the formed hanger geometry 55 provides a closed loop to support the swing cord in any position. An optional washer 56 (shown in cross section) is used to provide a uniform bearing surface for the hanger formed geometry 55 against the mounting surfaces 52 and 53. Attachment of the swing main cord to the hanger is accomplished by looping the cord through the central opening in the formed geometry 55 as described in FIGS. 1, 1A and 1B to connect the continuous cord loop to the over head beam, or by the use of traditional hardware connected to the main cord such as a latch hook.

FIG. 6 describes an alternate embodiment of the system 100 that further incorporates a second supporting cord loop 104, having a length of approximately 53 inches. The second cord loop can be formed when the two ends of the cord overlap each other and each end is crimped to the main cord length via crimped oval wire sleeves 105. Another way to form the second cord loop is to add a fixed length cord that attaches in two places to the main cord loop 102 via crimped oval wire sleeves 105. The purpose for the second loop is to provide added support to the car seat carrier 4 at base portions 4 d and 4 e by supporting loops 103 and 104 as shown. Cinching strap 6 is positioned along the cord assembly of system 100 to add optional securing points to rigid portions of the car seat carrier including, the carrier arm 4 a or around the arm pivot joint 4 c. In the embodiment of FIG. 6, the car seat carrier arm 4 a can be positioned in its folded down position as shown in FIG. 6 or in its up right carrying position.

FIG. 7 describes the system in FIG. 6 but the supporting cord loop 103 engages slot 4 c of the cars seat carrier to adjust the incline of the seat 4

FIG. 8 depicts the attachment of a toddler car seat 110 into the system, cinching strap 6 secures to the car seat's seat belt restraint system (not shown).

Now that we have established the general variations for attachment and the concepts for use of reels and hangers the invention will be more obvious referring to the preferred embodiments as described in FIGS. 9 through 12. FIG. 9 depicts the preferred system components 120. The swing accessory 121 has a double reel comprised of reel 122 and reel 123 joined together by interface 124. Reel 123 has a cord 33 that retracts through opening 126. The cord is fixed to reel 122 via fitting 127. Cords 128 and 129 are both retractable together into reel 122, both cords 1228 and 129 are fixed to reel 123 via fitting 130. Cinching straps 6 are incorporated onto cord 128, there are adjustable slides 132 that are used to slideably position the cinching strap along cord length into a desired position. Cinching straps 6 slide over cord through grommet fitting 136. Cinching straps are secured by wrapping end 134 around desired point of attachment and inserting end 134 through end loop 135. The strap is then pulled snugly and fastened to itself using hook and loop properties. The system will be supplied with multiple hangers such as hanger 50 with washer 55 for installation into overhead beams without tools. The standard porch hangers 145 having open hooks 147 would be provided for user's option for hanging the system in a desired location. The sharp screw tips would be protected by vinyl caps 146. The system would also comprise a toy attachment 140 for the swing. Clips 144 are slidably positioned along string 143 to grip the cord in desired locations so the baby can view or play with ornaments 141 and 142. Ornaments may have sounds, lights and shapes that are appealing for babies. The system accessory will be contained within a carry pouch 149 for neat and compact portability.

FIG. 10 describes the preferred system attached to a single overhead hanger 50 installed into an over head beam 150 that has a ceiling cover 151. The reels 122 and 123 are attached together. The car seat carrier 4 is in a prone position for the baby to sleep. Toy attachment 140 is engaged onto cord 128. In this configuration the baby can easily rest. The single point attachment to the overhead beam allows the swing to generate a pendulum motion, where the baby can easily be swung front to back or side to side else a combination of the two. Also gentle tipping of the car seat carrier results in a gentle oscillation or rocking of the car seat without the swinging motion that is soothing to the baby.

FIG. 11 depicts an alternate attachment of the preferred embodiment of the system resulting in a partially inclined position of the car seat. Both cords 128 and 129 engage car seat slot 4 c and cords are secured to handle 4 a using cinching straps 6. In this configuration the car seat handle 4 a adds support, due to the multiple positions of the car seat handle, the inclined positioning of the car seat is adjustable, as is shown in FIG. 11A, by adjusting the handle 4 a down the car seat is positioned fully upright. The baby is now in an upright sitting position. In this position the baby can be easily fed as in a high chair, with the reels providing height adjustment.

To further describe the versatility of the system, FIG. 12 depicts the function of separating the reels 122 and 123. The reels are normally engaged via a twist lock interface where pin 161 from reel 123 engages a radial slot 160 on reel 122 (not shown), and vice versa. By separating the reels the cord 33 can engage two hangers 145 installed into an over head beam 150. The preferred spacing between hangers 145 is 16 inches. This configuration is more conducive to forward and backward swinging and for attachment to both car seat carriers and toddler car seats.

It should now be obvious to any one skilled in the art, that the swing system comprising main cords, supporting cords, cinching straps, the use of cord reels, cord end fittings and the overhead hanging methods of the new car seat swing apparatus can be arranged in other suitable embodiments that satisfy the claims while remaining within the true spirit of the invention.
